1 Claim. 1

This invention relates to spray nozzles and more particularly to anozzle for forming a mist which may be produced from relatively highpressure liquid.

An object of this invention is to provide a spray nozzle which includesa pressure chamber and a plurality of jet openings radiating from thechamber, the nozzle being formed of tempered metal which will withstandrelatively high pressures.

A further object of this invention is to provide a nozzle of this kindwhich includes a base plate of disc-shape and an apertured plate weldedor otherwise fixed to the base plate and also includes a dome-shapedchamber forming member which is welded to the apertured nozzle plate,the entire assembly being of welded construction so as to provide asubstantially unitary device which will withstand hard usage and can beused either in a horizontal position or any other desired position forforming a mist or fog which, when used in combat, may provide a coverfor troops or the like.

To the foregoing objects, and others which may hereinafter more fullyappear, the invention consists of the novel construction, combinationand arrangement of parts, as will be more specifically referred to andillustrated in the accompanying drawings, but it is to be understoodthat changes, variations, and modifications may be resorted to whichfall within the scope of the invention a claimed.

In the drawing:

Figure 1 is a detail top plan partly broken away and in section of anozzle constructed according to an embodiment of this invention, and

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Referring to the drawing, the numeral l designated generally a baseplate which is of discshape and which has secured to the upper sidethereof a nozzle plate, generally designated as I I. The nozzle plate IIis substantially ring-shaped having a substantially smooth innerdiameter 13 and the outer diameter or surface of the nozzle plate H isformed with projections or points [2, which merge with each other bymeans of a concave outer edge 14. The plate II is formed with a pair ofjet openings l5 and It in each concave surface I4, the inner ends of theopenings l6 opening through the annular inner edge 13 of the plate H. Adome-shaped top member I! is disposed on the upper side of the nozzleplate ll being secured thereto, as by welding l8 or the like.

The top member I! forms a pressure chamber 19 within which liquid underpressure is adapted so that an intake pipe 2| may be extended betweentheopen ends 20 of the plate II and is then formed on an angle, asindicated at 22, and welded or otherwise firmly secured to the plate Hand to the dome-shaped member H. The intake nipple or pipe 2| may be ofany desired length and may have coupling means at its outer end forcoupling the pipe or nipple 2| to a source of liquid pressure supply.Under combat conditions the nozzle structure hereinbefore described maybe used on a vessel being extended along the side of the vessel or atother suitable positions so as to form a fog in order to conceal thevessel. This device may also be used for other purposes for which aspray nozzle of this kind may be adapted.

The exact configuration illustrated is regarded as the optimum, but someof the desirable results inherent in this disclosure may be obtained byvarious slight modifications including some departure from the exactconfiguration shown, and it is therefore requested that the scope of theinvention should be regarded as limited only by the terms of the claim.

What I claim is:

A spray device of the class described, comprising a disc-shaped basemember, an annular fiat nozzle ring secured to the top surface of saidbase member and concentric therewith, the outer edge of said ring beingformed with a plurality of circumferentially spaced apart concaveddepressions, a dome member secured to the top surface of said ring toprovide a pressure chamber, a plurality of pairs of outwardly converginghorizontal nozzle bores formed through said ring, a pair of bores beingprovided for each of said concaved depressions and the outer ends ofsaid pair of bores being disposed symmetrically with respect to thecenter of the related depression whereby the portions of said ring onthe opposite sides of each of said depressions provide shields for theouter ends of said nozzle bores to prevent clogging thereof andpremature admixture of the fluid ejected from the pairs of bores.
